A video switch box connects multiple video devices, such as DVD
players, VCRs, video game systems, camcorders, satellite TV systems or
cable boxes, to a TV or audio system. The box allows you to switch
different video sources into your TV. Your TV only has to have one
input. By switching the box to the desired video source, you can select
the video device you want to use at the current time while maintaining
connections for all other video devices. No more swapping cables.

Video switch boxes come
in various styles with some having automatic switching capability. Some
have a built-in RF modulator and RF hookup. There are switches for
composite, S-video, component video, DVI and HDMI video/audio. Some
boxes are even remote controlled. The cost for the composite video
level box is very low and they are available
at electronics retail
stores
or online.

A "RF" modulator
